In September 2025, Texas SB 1145 transferred regulatory authority for land application of treated produced water from the Railroad Commission of Texas (RRC) to the Texas Commission on Environmental Quality (TCEQ). This is the most significant regulatory shift for Permian produced water reuse in decades — and the implementing rules are being written right now.

What's actually changing

Under the old RRC framework, land application of produced water for purposes like road dust suppression operated under relatively informal oversight. Under the new TCEQ framework, these activities require formal permits with specific effluent limits, groundwater monitoring requirements, and site suitability reviews.

TCEQ is proposing to implement this through amendments to Chapters 309 and 210 of the Texas Administrative Code. The proposed rules are in public comment through June 16, 2026, with a public hearing on June 15 in Austin and rule adoption targeted for August 2026.

What operators need to do now

• Assess whether any current produced water activities constitute "land application" under the new definition
• Review the proposed effluent limits — particularly for TDS, sodium, and trace metals — against current treatment capabilities
• Determine whether you'll need to apply for a permit and begin gathering site information and water quality data
• Consider filing a public comment if the proposed limits or monitoring requirements are operationally infeasible
• Consult a licensed environmental engineer about permit application timing relative to the August adoption date

The comment window is your chance to shape the rules

TCEQ must consider and respond to substantive public comments before finalizing the rules. Comments with operational data — treatment capabilities, volumes, costs — carry significant weight. The time to act is before June 16.

Until 2025, virtually all Permian Basin produced water was either injected into disposal wells or recycled for hydraulic fracturing within the oilfield. Texas HB 49 (effective September 2025) changed that — authorizing produced water reuse for non-oilfield purposes and establishing the legal framework for commercial supply agreements.

Lithium extraction — the highest-value pathway

Permian Basin produced water contains naturally occurring lithium at concentrations that support Direct Lithium Extraction (DLE). Companies including Element3 and LibertyStream/Select have active commercial projects targeting production in H1 2026. Lithium credits can potentially offset treatment costs, turning disposal into a revenue-generating activity.

The Texas Supreme Court's Cactus v. COG ruling (2025) confirmed that dissolved minerals in produced water belong to the mineral lessee — eliminating the ownership ambiguity that had slowed deal-making in this space.

Data centers — the volume opportunity

AI infrastructure buildout is driving massive data center development in West Texas. These facilities require large, reliable volumes of cooling water — and treated produced water at lower TDS specs (<500 ppm for cooling towers) is a viable substitute for freshwater that is increasingly scarce in the Permian. Several developers are in active water sourcing discussions for facilities in the Midland/Odessa area.

Power generation — co-location play

Thermoelectric power plants serving data center load, and emerging hydrogen production facilities, require significant cooling and process water. Co-locating with produced water supply sources creates a compelling cost structure and reduces freshwater dependency.

What producers should do

• Characterize your produced water — TDS, lithium concentration, chemistry profile
• Understand your volume and reliability profile — reuse buyers need predictable supply
• Engage a water treatment company to assess treatment pathway and costs
• Submit your supply profile via our producer intake form — we're building the connection infrastructure now

Produced water has been used for dust suppression on Permian Basin roads, pads, and construction sites for decades. It is available, familiar to field teams, and often cheaper than hauling freshwater into remote work areas. But under the proposed TCEQ Chapter 309/210 framework, dust control is no longer just an operational decision. It is part of the broader produced water land-application and reuse conversation.

The practical question is shifting from "Can we get water on the road?" to "Can we document the water quality, site conditions, application rate, and responsible party well enough to satisfy the new framework?" That affects operators applying their own produced water, contractors managing dust control, haulers moving water, and companies supplying treated produced water.

What changed under TCEQ Chapter 309/210

Texas SB 1145 transferred authority for land application of treated produced water from the Railroad Commission of Texas to TCEQ, effective September 1, 2025. TCEQ is implementing that transfer through proposed Chapter 309/210 amendments, currently in public comment through June 16, 2026.

For dust control, the proposed framework points toward formal TCEQ authorization, water quality standards, site-specific review, monitoring expectations, application-rate controls, and recordkeeping. Final requirements may change before adoption, but the direction is clear: informal produced water road application is becoming a documented compliance activity.

Roles and responsibilities matter

In many Permian dust-control situations, there may not be a true buyer and seller at all. An operator may generate the produced water, control the lease road or pad, and apply the water internally. In other cases, a water hauler, service contractor, midstream company, treatment provider, or third-party road operator may be involved. The compliance question is less about whether there is a transaction and more about who controls the water, who applies it, who controls the site, and who keeps the records.

• Operators applying their own water need to understand water quality, application areas, site conditions, recordkeeping, and who inside the organization owns compliance.
• Service contractors, EPC teams, and haulers need clarity on whether they are only performing field work or also carrying documentation, application-rate, or permit-related responsibilities.
• Water suppliers, midstream companies, and treatment providers may need to package lab data, source-water information, treatment performance, and delivery documentation in a way that operators can use for compliance files.

What field teams should prepare now

Even before final rules are adopted, operators can start organizing the information that will likely matter under the proposed framework. That preparation is useful whether the final permit pathway is broad, narrow, or phased in over time.

• Inventory current dust-control practices, water sources, application areas, and frequency of use
• Collect recent water quality data, including TDS, SAR, chloride, metals, bacteria, pH, and any treatment records
• Identify who controls the application site and who is responsible for records, permits, and operational decisions
• Document site conditions such as soil type, drainage, nearby surface water, water supply wells, and depth to groundwater where known
• Track volumes, dates, locations, and weather conditions for produced water application events
• Review whether commercial suppressants, treated produced water, freshwater, or blended approaches make sense by location and risk profile

Produced water vs commercial suppressants

Produced water can be attractive because supply is nearby and disposal alternatives are costly. Commercial dust suppressants can be attractive because they may reduce application frequency, improve surface performance, and simplify some water-quality questions. Neither answer is automatically right across the Permian.

The right choice depends on road use, soil conditions, traffic, wind exposure, water chemistry, treatment cost, documentation burden, and the operator's tolerance for compliance complexity. Under the proposed TCEQ framework, cost-per-barrel is only one part of the decision. Documentation and defensibility matter too.

Where to get help

Operators using produced water for dust control should review the proposed rules, compare current practices against the checklist materials, and talk with qualified advisors before making compliance decisions.

The TCEQ land application permit process for treated produced water is new, and the full implementing rules won't be adopted until August 2026. But understanding the framework now — and starting to gather the data you'll need — puts you well ahead of the curve.

Step 1: Determine if you need a permit

If you apply treated produced water to land for any purpose — dust suppression, irrigation, industrial use, or other land application — you'll need a TCEQ permit under the new Chapter 309/210 framework. This applies to both oilfield roads and non-oilfield land application.

Step 2: Characterize your water

You'll need a complete water quality profile including: TDS, sodium adsorption ratio (SAR), major ions (calcium, magnesium, sodium, chloride, sulfate), trace metals, total organic carbon, and bacteria. A certified laboratory in the Permian Basin can run this panel.

Step 3: Assess the site

TCEQ will require a site evaluation including soil type, topography, proximity to surface water bodies, depth to groundwater, and land use classification. A licensed professional geoscientist or engineer can prepare the site assessment.

Step 4: Determine treatment requirements

The proposed effluent limits under Chapter 309/210 are not yet final (they're in public comment through June 16). However, most operators will need at minimum: solids removal, bacteria treatment, and likely some form of desalination or dilution to meet sodium and TDS limits for land application.

Step 5: Prepare and submit the application

Once rules are adopted (target August 2026), TCEQ will publish application forms and guidance. Applications will typically require: water quality data, site assessment, treatment system description, monitoring plan, and financial assurance documentation.

Key timeline

On June 1, 2025, the Railroad Commission of Texas implemented the most significant overhaul to saltwater disposal (SWD) well permitting requirements since 1982. The changes — which apply to all new and amended permit applications in Permian Basin Districts 7C, 8, and 8A — were partly triggered by a May 2025 suspension of all deep disposal permits in the Northern Culberson-Reeves Seismic Response Area following a 5.4 magnitude earthquake.

The five key changes

• Expanded area of review (AOR): Extended from 0.25 miles to dual-buffer zones of 0.5 and 2 miles, reflecting modern understanding of pressure diffusion in disposal formations
• Wellbore integrity assessment: Operators must identify and evaluate all wellbore penetrations within the AOR for potential fluid migration pathways
• Pressure limits: Applications must demonstrate that injection pressures will not cause formation pressures to exceed fracture gradients of confining strata
• Volume limits: RRC will place caps on maximum injection volumes based on reservoir pressure conditions
• Seismicity buffers: Any disposal well permit application within 25 kilometers of a seismic event undergoes enhanced seismicity review

What this means for operators

The practical effect is a significantly higher bar for new SWD permit approvals — more data required, longer review times, and the real possibility of permit denial or volume restriction in seismically active areas. Operators in the Delaware Basin face the most exposure, given the concentration of seismic activity there.

The push toward recycling and reuse

These changes, combined with tightening pore space capacity in key disposal formations, are accelerating the economics of recycling and reuse. Operators who once relied on low-cost disposal now face rising costs and capacity uncertainty. Recycling for hydraulic fracturing has reached cost parity in many areas — and with disposal getting harder, the calculation shifts further.

For years, a fundamental question hung over the Permian Basin produced water market: who actually owns the water? The operator who produced it? The surface landowner? The mineral lessee? The ambiguity made it difficult to structure long-term commercial agreements and complicated financing for treatment and reuse infrastructure.

What Cactus v. COG decided

In 2025, the Texas Supreme Court ruled in Cactus v. COG that produced water belongs to the mineral lessee — unless a contract between the parties states otherwise. The court treated produced water as a byproduct of hydrocarbon extraction that falls under the mineral estate, not the surface estate.

Why this matters for beneficial reuse

The ruling makes it possible to do several things that were previously legally ambiguous:

• Structure long-term produced water supply contracts with known ownership rights
• Finance treatment infrastructure against a defined supply asset with clear title
• Negotiate produced water royalties or purchase agreements between mineral lessees and buyers
• Pursue lithium and mineral extraction agreements with clarity on who can grant extraction rights

Key caveats

The ruling explicitly preserves contractual flexibility — parties can negotiate different ownership terms in surface use agreements and oil and gas leases. The ruling also does not affect the liability of produced water generators to landowners for spills or contamination. And it doesn't address the ownership of minerals dissolved in produced water (the Cactus v. COG ruling clarified the water itself; mineral ownership questions remain in development).
